Michelle Obama had one incredible send-off as she made her final appearance on The Tonight Show as the first lady on Wednesday night. After making us laugh (and cry) with her spot-on thank-you notes, she proceeded to get serenaded by the one and only Stevie Wonder as he performed a special medley of his hits, "Isn't She Lovely" and "My Cherie Amour." Not only did he tailor the songs to be about her, but Michelle couldn't help but sing along with him. We are definitely going to miss sweet appearances like this when Michelle leaves the White House.
